Resumo: This study aimed to verify the psychometric properties of the Dysexecutive Questionnaire (DEX) through exploratory factor analysis (EFA), evidence of reliability, and convergent validity, in a sample of neurologically preserved older adults. Participants were 345 older adults who answered, in addition to DEX, a sociodemographic and clinical questionnaire, the Mini-Mental State Examination (MMSE), and two verbal fluency tasks. The EFA was conducted through Parallel Analysis based on the generation of a polychoric correlation matrix, as well as Pearson’s correlation between the DEX scores, age, education, MMSE, and verbal fluency tasks. According to the EFA, the extraction of two factors (“Inhibition” and “Social Regulation and Planning”) was suggested and DEX was negatively associated with age and MMSE. In conclusion, DEX presented a satisfactory factorial structure for older adults, which can be considered a reliable self-report measure for complaints of executive functions. Keywords:

Participaram 345 adultos idosos que responderam, além do DEX, um questionário sociodemográfico e clínico, o Miniexame do Estado Mental (MEEM) e duas tarefas de fluência verbal. A AFE foi conduzida por meio de análise paralela com base na geração de matriz de correlação policórica, bem como correlação de Pearson entre os escores do DEX, idade, escolaridade, MEEM e tarefas de fluência verbal. A AFE sugeriu a extração de dois fatores (“Inibição” e “Regulação Social e Planejamento”) e o DEX associou-se negativamente com a idade e com o MEEM. Conclui-se que o DEX apresentou estrutura fatorial satisfatória para adultos idosos, podendo ser considerado uma medida confiável de autorrelato para queixas de funções executivas.El objetivo de este estudio fue verificar las propiedades psicométricas del Cuestionario Disejecutivo (DEX) a través del análisis factorial exploratorio (AFE), evidencias de confiabilidad y validez convergente, en una muestra de adultos mayores preservados neurológicamente. Participaron 345 adultos mayores que respondieron, además del DEX, un cuestionario sociodemográfico y clínico, el Mini Examen del Estado Mental (MEEM) y dos tareas de fluidez verbal. La AFE se realizó mediante Análisis Paralelo basado en la generación de una matriz de correlación policórica, así como la correlación de Pearson entre las puntuaciones del DEX, edad, nivel de escolarización, MEEM y tareas de fluidez verbal. La AFE sugirió la extracción de dos factores (“Inhibición” y “Regulación y Planificación Social”) y el DEX se asoció negativamente con la edad y con el MEEM. Se concluyó que el DEX presentó una estructura factorial satisfactoria para adultos mayores, lo que puede considerarse una medida de autoinforme fiable para las quejas de funciones ejecutivas.2021info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://hdl.handle.net/10316/101033http://hdl.handle.net/10316/101033https://doi.org/10.1590/1413-8271202126nesp10eng2175-35631413-8271Oliveira, Camila Rosa deLima, Margarida Maria Baptista Mendes Pedroso deBarroso, Sabrina MartinsArgimon, Irani Iracema de Limainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-07-27T20:37:31Zoai:estudogeral.uc.pt:10316/101033Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:18:17.325850Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
